Design And Implementation Of Visualization Management System In Network Orchestrator

In recent years,with the increasing reliance on the Internet and the increasing scale of the network infrastructure,it is becoming increasingly difficult for traditional network architecture to meet the requirements.The emergence of new technologies in the industry,such as Network Function Virtualization,Software Defined Network and Network Orchestrator Technology,has become the key to change.On the other hand,the development of Web technology also provides a new idea for network management.This thesis relies on the project of "Network Definable virtualized switching network platform" of State Key Laboratory Of Networking And Switching Technology,and puts forward a design and implementation of lightweight network orchestrator visualization management system.With new features,like single page application,Canvas and other new features of HTML5,it provides the users of lightweight network orchestrator with a user-friendly visualized management system which makes the orchestration more intuitive.At the beginning of this thesis,it introduces the research background and research significance of lightweight network orchestrator,and then identifies the main work of visualization management system.Secondly,it briefly introduces the architecture mode and new web technology used in the design and implementation of visualization management system.Then this thesis carries on a comprehensive demand analysis to the lightweight network orchestrator and summarizes the function of the visualization management system.After that,this dissertation introduces an overall architecture design followed by an abstract design of each module of visualization management system,and also describes the interaction between visualization management system and other lightweight network orchestrator subsystems.Based on those design,this thesis has carried on a detailed design of the visualization management system and elaborates the class diagram,the detailed workflow,the interactive interface and the system database design of each function module hierarchically.The relevant coding work was implemented and the entire lightweight network orchestrator was deployed in an experimental network environment.White-box testing and System testing were performed on the visualization management system.Finally,this thesis summarizes the work of the entire thesis and states the vision of future work.
